To a whom it;1ntty concrn.-.

Be it known that I,"A DREwMoRRIssoN, a citizen of the United States,residing at- Coleman, in the county of 'Coleman "and State of Texas,have invented new and useful Improvementsin Windmills, of which thefollowing is a specification.

My'invention relates to newand useful improvements in windmills, andmore particularly to the mechanism for transmitting motion from thewheel-shaftto-the pump-rods.

Objects of the invention are to provide means whereby a double stroke ofthe rods may be obtained duringonere fvolution of the shaft and toemploy a'novel connection between said rods and the shaft;

With the a-boveandbther Objects in view the invention consists inithenovel construction and combination of parts hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings,showing the preferred form of; my invention, and in which 1 Figure 1 isa perspective View of a portion of a windmill embodying my improvements.Fig. 2 is an enlarged section through the millhead, showing theconnections between the shaft and pump-rods; and'Fig. 3 is a similarview of a modification, orie'of the connectingsleeves being show'nirielevation; I

Referring to the figures by'numerals of reference, 1 is a derrick ofsuitable construction, upon which is pivotally mounted a millhead2,.having a vane 3 and a wind-wheel t thereon. An auxiliary *vane 3,having a weight 3* connected thereto, is arranged upon the head 2,and'the 'same, together with vane 3, is adapted to be; operated byal.lever 4t, mounted upon the shaftvt? of vane 3. A cord 4 extends fromtheleve'r, whereby the same may be moved by aper'son at the base of thederrick; The shaft'5 of this wheel is preferably provided'withtwooppositely-extending cranks 6, arranged above the vertical passage 7,formed in the head 2, and each connected to a pitman 8. The-bottom ofthe passage 7 is closed by a disk 8 having a central aperture 9, withinwhich "is-slidabIy'mounted atube 10, held in a vertical position by apendant 11, within which the tube is mounted. A flange 12 is formed atthe upper end of this tube, and it is connected to one crank 6 byapitman 13. The other crank' on shaft 5 is connected by a pitman: 8 to ahead 14, formed at the upper end of a rod 15,and this rod is slidablymounted within and extends through the sleeve 10. V I

A disk 16 is arranged at the lower end of tube 10 and provided in itslower face witha circular recess 17. This recess is adapted to receivethe upper end ofa pump-rod 18, and the rod is held in position thereinby means of a sleeve 19, bolted or otherwise secured thereto. Thesleefvef is secured to the rod at a distance from the endthereof equalto the depth of recess17, and an L-shaped arm 20 extends laterally fromthe end of the sleeve and is formed integral with the plate 2l,whichextends over and is slidablymounted upon a flange 22,.inclosingthejdisklo. This arm 20 serves to hold'theend offthe rod 18 at all timeswithin the recess l'r' andat' the same time permits the disk'to revolvewithout necessarily moving the rod 18 out of vertical position. A

similar but smallerldisk 23 is formed at the lower end of the rod 15,and this is also provided with a recess 24 in its lower face, whichreceives the end ofv'a second pump-rod 25. The flange 26, inclosing thedisk 23, projects under a plate 27,'simil'a'r to but smaller than theplate 21 and forimed integral with an L- shaped arm 12l8,projectingflaterally from a sleeve 29, detachably secured to the rod 25.

In Fig. 3 I have shown a modified form of mechanism for transmittingmotion from the wheel-shaft to the pump-rods. In this modification Ihavesubstituted gear-wheels for the cranks 6. *Two gears 30 are securedto the shaft Sand mesh with larger gears 31, each of which isprovidedupon its inner face with a wrist-pin 32,1 engaging one of thepitmen 8. These pins'are arranged so as to lower the pitmen alternately.By this construction of wihdmill'it will be seen that one downwardstroke of each pump-rod, or, in other words, a total of two downwardstrokes, is secured during each revolution of the wheel 'shaft 5; also,as the .-millhead revolves upon the derrick 1 the pump-rods will remainin their ordinary, upright positions, while the disks 16 and 27 revolvewithin the arms of the sleeves connected thereto. As

these sleeves are detachably secured to the rods, said rods can bequickly placed in position within the disks, where they are securelyheld throughout the operationof the mill.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and-I therefore reserve the right tomake such changes as fall within the scope of my invention.

Having thus described the invention, what is claimed as new is- 1. In awindmill, the combination with a reciprocating rod and means forimparting motion thereto, of a recessed disk at one end thereof, aflange inclosing said disk, apnmprod extending into the recess, a sleeveupon said rod, an arm thereto extending below the flange and a plate onthe arm overlapping said flange, whereby the rod is secured within thedisk but said disk is permitted to rotate.

2. In a windmill, the combination with a tube and a rod extendingthrough and slidably mounted within said tube; of a recessed disk at thelower end of both the tube and the rod, a flange inclosing each disk, apumprod extending into the recess of each disk, and means upon each rodfor engaging the flange of its disk, but permitting rotation of saiddisk.

In testimony whereof I affix my signature in presence of two witnesses.
